Figure 2. — Profile of HF-HRV after IN-OT in a resting-state paradigm with eyes-closed (left) and eyes-open (right) conditions. Significant pairwise comparisons (IN-OT vs placebo) at specific time windows are marked with an asterisk (*). Eyes-closed time windows: 1 = 15–20 min; 2 = 30–35 min; 3 = 45–50 min; 4 = 60–65 min; 5 = 75–80 min; and 6 = 90–95 min. Eyes-open time windows: 1 = 20–25 min; 2 = 35–40 min; 3 = 50–55 min; 4 = 65–70 min; 5 = 80–85 min; and 6 = 95–100 min. Error bars: Standard error. HF-HRV: high-frequency heart rate variability; IN-OT: intranasal oxytocin; HRV: heart rate variability.
